In 1916, Albert Einstein published his famous general theory of relativity, which contains the rules of gravity and provides the basis for modern theories of astrophysics and cosmology. For many years, physicists, astrophysicists and mathematicians have striven to develop techniques for unlocking the secrets contained in Einstein's theory of gravity; more recently, computational science research g...

In collaborative virtual reality (VR), the goal is to reproduce a face-to-face meeting in minute detail. Teleimmersion moves beyond this idea, integrating collaborative VR with audio- and video-conferencing that may involve data mining and heavy computation. In teleimmersion, collaborators at remote sites share the details of a virtual world that can autonomously control computation, query databas...

High-speed, wide-area networks have made it both possible and desirable to interconnect geographically distributed applications that control distributed collections of scientific data, remote scientific instruments and high-performance computer systems. Historically, performance analysis has focused on monolithic applications executing on large, stand-alone, parallel systems. In such a domain, mea...

Because floating-point computation is the heart of 3D geometry, speeding up floating-point computation is vital to overall 3D performance. To produce a visually perceptible difference in graphics applications, Intel's 32-bit processors-based on the IA-32 architecture-required an increase of 1.5 to 2 times the native floating-point performance. One path to better performance involves studying how t...

Software reality is more about people working together than it is about defined processes; it's more about science than it is about computer science; it's more about understanding than it is about documentation; it's more about inquiry than it is about metrics; it's more about skill than it is about methods; it's more about becoming better than it is about being good; and it's more about being goo...

Most researchers who perform data analysis and visualization do so only after everything else is finished, which often means that they don't discover errors invalidating the results of their simulation until post-processing. A better approach would be to improve the integration of simulation and visualization into the entire process so that they can make adjustments along the way. This approach, c...

Smart cards are beneficial in some scenarios, but they are not the security panacea that some people believe them to be. In some user environments, the costs and inconveniences clearly outweigh the potential benefits of using smart cards

Our increased ability to model and measure a wide variety of phenomena has left us awash in data. In the immediate future, the authors anticipate collecting data at the rate of terabytes per day from many classes of applications, including simulations running on teraFLOPS-class computers and experimental data produced by increasingly more sensitive and accurate instruments, such as telescopes, mic...

Reflects on the contributions made by object-oriented (OO) development and its future. Don't blame OO programming in general for the limitations of those who don't know how to apply the principles! Only a minority of the industry has tried seriously and without compromise. The experience of others-those who go at it half-heartedly-is not a good technology. So the author's answer to the OO critics ...
